The Stelo Glucose Biosensor System includes an applicator with an all-in-one sensor/transmitter, overpatch, and Stelo app (available on both iOS and Android). The sensor is a small and flexible wire, which is inserted by the applicator under the skin. The sensor has an expected wear time of up to 15 days‡ with an extended 12-hour grace period. The transmitter is connected to the sensor and is worn on the body using the patch and overpatch. The transmitter estimates the glucose values and sends them to the Stelo app via Bluetooth. The Stelo app displays the current glucose values and the direction the glucose is heading. The information can help users make better decisions about food and activity relating to their glucose management.
